PAUSES — Analysis of pauses, utterances, loudness and dynamics

Determines the distributions of speech parameters, such as duration of pauses and utterances, energy and dynamics, or mean vocal pitch, in a speech recording, or in a set of recordings. Speech parameters can be analysed within individuals or across individuals for a prespecified experimental condition. All parameter distributions can be visualized through bar charts.

Fig. 21: Mean utterance duration and mean pause duration describe the statistical properties of speech flow. These parameters are used to test the hypotheses that (1) patients speak more slowly during depression than they do after recovery, and (2) number and duration of temporary breaks decrease with recovery from depression. It is worth noting, however, that speaking behavior is a complex issue that cannot be reliably described by a single parameter.
